1, cold dew, the seventeenth of the twenty-four solar terms, belongs to the fifth solar term in autumn. Cold dew is the season of late autumn, and the cold dew solar terms mark the transition from cool to cold. As the saying goes, cold dew is everywhere in Coody Leng. As the cold grows, everything is gradually bleak. The rainy season is over and the weather is dry in most parts of our country.
2. The cold dew solar term begins at the end of the first ten days of 10 and ends at the end of 10. The direct point of the sun continues to move southward in the southern hemisphere, and the angle of sunlight in the northern hemisphere begins to tilt obviously. The solar heat received by the ground is significantly reduced compared with that in summer, and the influence caused by the sphere of influence of cold air can sometimes extend to South China. The rapid temperature drop is a feature of the cold dew solar terms. After the autumn wind and autumn rain brought by a strong cold air, it is common for the temperature to drop by 8℃ and 10℃. However, most of the stormy weather does not last long, and it is controlled by cold and high pressure, with warm days and cool nights, and crisp autumn days.
